Definitions
- the disclosure relates to a biomass burner.
- biomass fuel As a clean energy, biomass fuel has been used by many flue-cured tobacco producing countries. Traditionally, granular biomass fuel is put into a coal-fired furnace for direct combustion and heating. Due to the low density of granular fuel, a large number of combustible gasification gases escape from the chimney, leading to thermal loss. In addition, the harmful nitrogen and oxygen compounds produced in the combustion process of biomass fuel are much higher than that of coal combustion in the conventional biomass furnaces.
